I was just trying this morning to netboot the box with the ata drivers
disabled in the kernel (I cant disable them in the BIOS) and the amr card
removed, and it at least gets to the point where I need to mount / via
nfs. However, trying to type in the serial console is as if the cable were
bad. Half the chars dont show up and 1/3rd are wrong.
Anyways, here is the trace. Let me know if there is other info
OK set hint.apic.0.disabled=1
OK boot
